To all whom it may concern:

Be it known that I, LoUIs'H. Maren, a citizen of the United States ofAmerlca, and

resident of Johnstown, in the county of- Cambria and State of Pennsylvania, have invented certain new 'anduseful Improvements in Heaters for Automobile-Radiators, of which the following is a specification.

This invention relates to electric heaters and particularly to a device designed to heat radiators of gaso-lene engines and to prevent freezing of the contents of the same.

An object of this invention is to provlde novel means which may be applied to a ra-' diator preferably in the front. thereof to be electrically heated so that the heat radiated therefrom may retain the temperature of the water or other liquid in the radiator above the freezing point. v

A; still further object of this invention is to provide a device of the character indicated which may be readily applied to or removed from an automobile and whichmay be utilized in connection with ordinary service electric current or in connection with a source of electricity carried by the automo-' bile.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed. p

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification,

wherein like characters denote correspond ing parts in the several views, and in which- Figure 1 illustrates a view in perspective of a fragment of an automobile with the invention applied thereto; Fig. 2 illustrates a view in elevation of the inner face of the heater; Fig. 3 illustrates a section on the line 3-3 of Fig. 2; Fig. 4 illustrates a View in elevation of a fragment of the heating element employed for utilizing the electricity; and Fig. 5 illustrates a sectional view on the line 5-5 of Fig. 4.

In these drawin s 6 denotes a radiator of an automobile which may be of any usual construction showing the heater 7 applied thereto andsecured by fastenings 8 which may be in the form of rivets, bolts, or other anchoring elements.

' The heater. comprises preferably a rectangular casing9 w1th flanges 10 at the end thereof. provided with openings 11 to receive thefastenings 8. The casing 9 is designed to receive a heating element comprising an asbestos or other non-inflammable covering 12 for the conductors of electricity 1 3, the said conductors of electricity being preferable that the heating element be flexible so that it can be folded into the recepta'cle 9 as shown in Fig. 3.

The receptacle 9 has a heating element retaining member comprising a rectangular frame 15 with flanges 16 resting on the face of the sides and ends of the receptacle 9, the said frame being provided with a series of ribs 17 attached at their ends to the frame, the said ribs lying approximately parallel and obliquely, theinner edges ofthe said ribs being adapted to bearagainst the heating element for the purpose of retaining it in position' and the interstices between the said ribs permittin the circulation of heated air and the said 1 1bS further actin as conductors of heat, so-that their outer e ges being in contact with'the front of the radiator heat from the said heating element is communicated to the radiator by the radiation of the heat through the ribs and by the circulation of the heated air. I It will be observed that the frame 15, is rovided with recesses 18 at its corners for t e accommodation and passage therethrough of the feed wire.

' I claim 3 -1. In' a radiator heater, a receptacle having end flanges, a heating element therein, a retaining member for the heating element comprising a frame fitting in the receptacle, ribs having their ends securedto the frame, said ribs lying obliquely in the said frame and having their inner edges in contact with the heating element and means for securing the heater to a radiator of an automobile.

2. In a'radiator heater, a receptacle having end flanges, a heating element therein, a retaining member for the heating element comprising a frame fitting in the receptacle having recesses in its edge for the passage therethrough of conduct-ms 50? the heating In testimony whereof, I hereamm afix my eglflemfgnt, ribs gmving theiy eildls sicured 1 signature in the presence of two Witnesses. be mmesai risllin 0111 m int/e said frame and hawing th eir im i wr dlggs in LUUIS MAYER contact with the heating element, and means Witnesses:
